Use Complete Sentences

A complete sentence expresses a complete thought. It has two parts: the subject and a predicate.

Inventors Subject solve problems. Predicate

To find the parts in most sentences, ask yourself:

  • 1. Whom or what is the sentence about? Your answer is the subject.

  • 2. What does the subject do? Your answer is the predicate.
